Care and Maintenance
If you notice that the time display is beginning to fade, or if it has completely disappeared, replace the batteries. Replace both batteries at the same time and do not mix different types of batteries. Do not leave exhausted batteries in the clock for a long period of time. They may eventually leak and cause damage to the clock itself or to the surface the clock is placed on.
Please dispose of the exhausted batteries properly.
Note: After replacing the batteries the clock will return to its original default settings. It will be necessary to reset the time and alarm settings.
